Abstract

Purpose: The purpose of this investigation was to design and implement a prototype physician workstation, called Portfolio, as a platform for developing and evaluating, by means of controlled observer studies,user interfaces and interactive tools for analyzing and managing digital portal images. The first observer study was designed to measure physician acceptance of workstation technology, as an alternative to a view box, for inspection and analysis of portal images for detection oftreatment setup errors. Methods and Materials: The observer study wasconducted in a controlled experimental setting to evaluate physician acceptance of the prototype workstation technology exemplified by Portfolio. Portfolio incorporates a windows user interface, a compact kit of carefully selected image analysis tools, and an object-oriented data base infrastructure. The kit evaluated in the observer study included tools for contrast enhancement, registration, and multimodal image visualization. Acceptance was measured in the context of performing portal image analysis in a structured protocol designed to simulate clinical practice, The acceptability and usage patterns were measured from semistructured questionnaires and logs of user interactions. Results: Radiation oncologists, the subjects for this study, perceived the tools in Portfolio to be acceptable clinical aids. Concerns were expressedregarding user efficiency, particularly with respect to the image registration tools. Conclusions: The results of our observer study indicate that workstation technology is acceptable to radiation oncologists as an alternative to a view box for clinical detection of setup errorsfrom digital portal images. Improvements in implementation, includingmore tools and a greater degree of automation in the image analysis tasks, are needed to make Portfolio more clinically practical.
